Fiber Optic Networks: The Nervous System of Smart Cities A smart city integrates digital technologies into urban infrastructure to improve the quality of life for citizens, enhance operational efficiency, and reduce resource consumption. However, none of these smart applications-from IoT sensors to AI-powered analytics-can function without a robust, high-bandwidth, low-latency communication network. This is where fibre optic cables come into play. 1.1 Unmatched Bandwidth and Speed Unlike traditional copper-based networks, fiber optic technology transmits data as pulses of light through thin strands of glass or plastic optical fibres. This allows fiber networks to carry
